Abstract: IMPROVED DATA TRANSMISSION SYSTEM WITH ERROR CORRECTING DATA ENCODING                          ABSTRACT OF THE DISCLOSURE       A multi-phase communication system for simultaneously trans-mitting plural binary digits employs one or more error-check bits which perform an encoding on the conveyed information over a plurality of digit intervals.  The information and error check digits are then communicated via a transmission channel -as by amplitude modulating phase-orthogonal carriers.    Upon reception, the incoming information and error check digits are decoded, and supplied to error syndrome circuitry which corrects errors which may arise from time to time during data transmission.

Abstract: A FIBER OPTIC STAR COUPLER            Abstract of the Disclosure A fiber optic star coupler particularly for use in providing optical interconnects between circuit boards has a light mixer into which input and output fibers are inserted.  The mixer has rectangular cross-section passage, an interior surface of which is highly reflecting.  The mixer is long enough to promote a degree of internal reflection of light from any one of the input fibers sufficient that the corresponding light intensity reaching the output fibers is substantially uniform.  In an optical interconnect arrangement, interconnection between circuit boards in a rack or cabinet is achieved by mounting light emitting and light receiving units on each board and leading fibers to which the units are fixed to the fiber optic star coupler so that light from the emitter units enters one end of the light mixer and fibers leading to the receiver units enter the opposed end of the light mixer.  The fiber optic star coupler is substantially cheaper and more easily manufactured than known fiber optic star couplers using a polished glass slab as a light mixer.   - i -

Abstract: ABSTRACT OF DISCLOSURE An athletic shoe having a sole bottom which is contoured in the region of first foot strike along the lateral border to provide an arcuate landing surface which curves upwardly toward the lateral side edge of the sole and away from the ground surface and which is radiused about an axis coinciding with an effective, average subtalar axis. The sole may additionally be  contoured along the rear heel portion in the region of first foot strike for straight heel strikers to provide another arcuate landing surface which curves upwardly toward the rear edge of the sole and which is radiused about a transverse axis coinciding with an average ankle axis.  The sole bottom is formed with separate sets of gripping ribs which are oriented in such a manner that traction is enhanced for a range of toe out angles in the toe off range, is maximized for an average toe out angle along the lateral border and is maximized for a zero toe out angle in the rear heel region.

Abstract: ABSTRACT OF THE DISCLOSURE:         A system is described with which the consumer can make his own high quality cigarettes free from the disadvantages of manual rolling or stuffing by the consumer or the use of any device.  The system includes a manufac-tured prefabricated sheath tobacco skein which is open at the end faces and a skein-like tobacco filling which can be transferred by means of a plunger enclosed in the packet into a cigarette paper shell.  The sheathed tobacco skein is selectively introduced into a prefabricated cigarette shell of known type or a cigarette paper gummed around said skein and the skein-like tobacco filling is then transferred with the aid of the plunger by being pushed out of the sheath into the cigarette shell or the shell gummed together from cigarette paper.          The sheathed tobacco skein ("cigarette tobacco cartridge") can be provided at its one end with a movably inserted or attached plug which provides an additional guarantee of the required non-smokability of the cigarette tobacco cartridge and facilitates the handling of the cartridge by the user in the making of the cigarette.  The sheathed tobacco skein may have a reinforcement ring for further improvement and facilitating of the handling by the user.

Abstract: ABSTRACT OF THE DISCLOSURE           An exhalation valve is disclosed having an inlet, an outlet and a diaphragm movable between closed position covering the inlet and an open position away from the inlet.  The valve includes a bias means comprising a sealed chamber containing a gas acting upon the diaphragm and urging the diaphragm to its closed position.  An opening means in said sealed chamber conducts a control pressure to chamber to create the bias acting against one side of the diaphragm.  The diaphragm comprises a flexible peripheral portion and a semi-rigid plunger.  The plunger has a projection adapted to move within a confined space to align the diaphragm and provide damping to its movement.  The flexible peripheral portion of the diaphragm has a specially shaped cross-section comprising two attached cantilever sections that reduce the effective resistance to motion between open and closed positions.  In the preferred embodiment, the plunger is an insert that fits into and is retained by the flexible peripheral portion.

Abstract: ABSTRACT OF THE DISCLOSURE   A one-piece truck bed liner which is rollable into a generally cylindrical mass for easy handling, storage and shipping. The liner includes a first section engageable with the floor of the truck bed and a second section engageable with the front wall of the truck bed with the first and second sections connected together by a hinge portion permitting complete pivotal movement between the sections. The liner sections are capable of movement into a position wherein they are coplanar and, therefore, the liner may be laid out completely flat outside the truck bed. The liner includes a first set of ribs on one side thereof for supporting cargo and permitting easy cleaning of the truck bed compartment. Further, the liner includes protrusions or transversely disposed ribs on its underside which bridge between the inverted channels on the truck bed floor to provide strength to the liner and to prevent substantial sagging of the liner into the troughs in the truck bed floor. This bridging effect also permits air to circulate along the truck bed floor to prevent moisture retention between the liner and bed floor thereby reducing the possibility of rusting and corrosion.
